Fujita makes comments during interview with former director, cast
Director Yoichi Fujita revealed in an group interview with the staff and cast of the Gintama anime series that he will not be working on the series this spring. He participated in the interview with former Gintama series director Shinji Takamatsu, voice actor Tomokazu Sugita (Sakata Gintoki), and voice actress Rie Kugimiya (Kagura) in the February issue of Tokuma Shoten's Animage magazine, which shipped on Saturday. Fujita did not indicate if another director will take his place, or if the Gintama anime will end. Fujita took over as Gintama's director from Takamatsu during the current third year of the anime, and Takamatsu has since been listed as the project's supervisor. When the magazine's interviewer asked Fujita and Takamatsu about how they are doing, they responded with the following:

Takamatsu: This is the first time in a long while that I haven't been busy directing at the beginning of a new year, so I like to do something relaxing. After all, directing work has gotten so hectic. Well, how about you, Fujita-kun?
Fujita: For starters, I won't be working this spring, so I think I'll be going to the Hello Work office. ["Hello Work" is the euphemistic name for the Japanese government's employment service centers.]

Everyone: ….

Fujita and Takamatsu jointly directed the Gintama series from episodes 100 through 105, before Takamatsu handed the reins of the production to Fujita. Fujita had previously directed episodes of Kekkaishi, Cluster Edge, and Onmyou Taisenki. Takamatsu had overseen After War Gundam X, School Rumble, and several series in Sunrise's Brave robot franchise.

The Gintama action comedy follows a quirky samurai in an alternate-history Japan, where aliens overlords have banned sword-carrying. While the Gintama anime's storyline has been gradually catching up with the storyline of Hideaki Sorachi's original manga, the animation studio Sunrise has not officially announced that it is ending the anime. Viz Media published the ninth volume of the manga in November, while the Crunchyroll website began streaming the latest anime installment, #139, last week.

Aw man i really wish Gintama dosen't end its the best comedy in anime that does so many parodies of anime that makes you laugh so much if you know them.The only reason I actually joined crunchyroll was for gintama episodes and also I heard that before they would end they would do a Sakamoto arc, an Otose arc, and a Sacchan arc before he wraps things up so im guessing at least about 170 or more

No............................... Please don't end.. Gintama must deserves more love..... it may not be as popular as Bleach/Naruto/One Piece outside Japan (which I don't understand why)..... but I think it's popular enough in Japan itself.. let's hope it will not end so soon...

i take it the anime is going into a break like d grayman i hope
well we haven't seen all the old ones yet and maybe by the time we got all the sub ones they will start doing again
how long will gintoki and the gang do goofy stuff last and when will or have we past the half way point of gintama, will we know about his past, what kind of ending will it be and finally, will gintaki have a cool crossover with bleach so they have a good filler for once and gintoki do dumdum dummmm a sword release (whatever)
find out for yourself

haha.. if Gintama ever have a crossover with Bleach.. that will certainly help Bleach... Bleach s*** at fillers... nowadays.. even their 'normal' episodes are getting draggy and long winded with the overly long recap... -.-

are you sure d gray man is on hiatus?

I like both Gintama and D gray man (I love Gintama more).. there are still a lot of room for more stories and arcs.. so I hope they will continue..

"...the animation studio Sunrise has not officially announced that it is ending the anime"

i knew those were only rumors about gintama ending. nobody ever said anything about ending it! and also in kale1doscopes post from above they only say that both directors, the former one and the current one, just need a break from work.
so my guess is, that either they are going to continue it later this year with the old directors or a new one will show up to take over the project.

maybe they really need a break now cause they don't wanna use made up fillers like bleach always does etc.
i mean that wouldnt really work with gintama anyway since there is no real story and every episode kinda feels like a filler, if you know what i mean

if i remember correctly there was even a episode where gin-san explained the problems of manga-adapted animes who are faster than the released chapters which always leads to fillers

It would be a crying shame if Gintama ends now. Because of this simple fact. The entire problem of Takasugi still hasn't been resolved. If anyone who has been watching this series as long as I have, Takasugi and his cronies (Bansai, girl with guns and feminist) are still around but hasn't been shown yet.

There should be at least one last arc involving Takasugi and his group along with Gin-San and company, with Otae, Katsura, Matsudaira and the rest of the shinesengumi, Baka-Oji and Kyuubei. (Because it would be interesting if she crosses swords with Takasugi let alone her dojo take on Takasugi's group)
